Abstract:
Objective To explore the correlation of preoperative D-dimer (DD) level with prognosis in Chinese esophageal cancer patients. Methods PubMed, EMbase, Web of Science, Cochrane Library, CNKI, VIP, Wanfang, SinoMed databases were searched to identify potential studies which assessed prognostic value of preoperative DD level in Chinese esophageal cancer patients from the establishment date of each database to March 20, 2019. The Stata 12.0 software was applied to conduct the meta-analysis and the hazard ratio (HR) with 95% confidence interval (CI) was combined to evaluate the relation between preoperative DD level and survival of Chinese esophageal cancer patients. Results A total of 5 studies involving 1 277 patients were included. The quality score of each study was ≥6 points. The results showed that the elevated preoperative DD level was significantly associated with poor overall survival (OS, HR=1.49, 95%CI 1.05-2.10, P=0.025) and cancer-specific survival (CSS, HR=1.83, 95%CI 1.39-2.42, P<0.001). However, no significant relation of preoperative DD with disease-free survival (DFS) was observed (HR=1.55, 95%CI 0.89-2.70, P=0.125). Conclusion High preoperative DD level may be an independent prognostic factor for Chinese patients with esophageal cancer. More prospective studies with bigger sample sizes are still needed to verify our results.
